A brain computer interface (BCI) system predicts text based on input and output signals obtained in relation to an individual that are informative for determining an individual's neurobiological activity. The BCI system applies a first predictive model to the input signal and a second predictive model to the output signal. The first predictive model predicts the forward propagation of the input signal through the individual's head whereas the second predictive model predicts the backward propagation of the output signal through the individual's head. Each of the first predictive model and second predictive model predicts characteristics of their respective signal at a common plane such as the cortical surface of the individual's brain. The BCI system predicts text by applying a third predictive model to the predicted signal characteristics at the common plane outputted by the first predictive model and the second predictive model.

Predicting text by reconstructing neuroimaging signals

A brain computer interface system interprets an individual's neural signals to predict specific phonemes, words, or sentences, thereby enabling the individual to communicate with others through unspoken methods. Specifically, a brain computer interface system captures neural signals from an individual at mesoscopic resolutions using optical neuroimaging techniques. The system applies the captured neural signals to multiple predictive models that have been trained on neural signals captured from previous individuals. The predictive models output predictions as to a phoneme or word that corresponds to the captured neural signals. Therefore, the individual can communicate through the brain computer interface system by only providing neural signals without using verbal, expressive, or physical means.
